◮ Measurements taken with membrane conditioned to 23°C, 50% RH for 24h.

◮ Conductivity measurement taken at 23 °C, 100% RH.

◮ A base titration procedure by using the caustic soda measures the equivalents of sulfonic acid in the membrane, thus calculating the acid capacity or equivalent weight of the membrane.

◮ Water content of membrane conditioned to 23 °C and 50% RH (dry weight basis).

◮ Water uptake of dry membrane conditioned in water at 100 °C for 1 hour (dry weight basis).
